Answer:
(d) not enough info
Explanation:
because it doesn't specify where the strings are attached
if it was the two ends of the rod then T1 would be equal to T2
surface wave of water is due to the disturbance of medium particles
this is also known as mechanical waves
In mechanical waves we need a mechanical medium to disturb the medium particles which will produce the disturbance
While electromagnetic waves do not require any medium and it can propagate through vacuum
Electromagnetic waves are propagation of electric and magnetic field which is due to oscillation of charge.
So electromagnetic field requires to and from motion of charge particle in which time dependent electric field will induce magnetic field and then they induce each other and propagate in the medium
Answer:
The magnitude of the net electric field is 
Explanation:
Given that,
Charge density 
Charge density 
Distance 
Distance 
We need to calculate the magnitude of the net electric field
Using formula of electric field


Put the value into the formula


Hence, The magnitude of the net electric field is
